Kant, Duty and Moral Worth tackles the debate over whether or not Kant said moral actions have worth only if they are carried out from duty or whether actions carried out from mixed motives can be good. Stratton-Lake offers a unique account of acting from duty which utilizes the distinction between primary and secondary motives. He maintains that moral law should not be understood as normative moral reason but as playing a transcendental role. Thus, a Kantian account of moral worth is one where the virtuous agent is one who is responsive to concrete particular considerations while preserving an essential role for universal moral priniciples.
